Your existing auto insurance or credit card may already cover rental cars
You do not automatically need to buy the rental company's insurance. Most people are already covered in one of three ways: through their personal auto insurance policy, through their credit card's rental car protection, or through their employer's policy. Before you pay extra at the rental counter, check what you already have.
The rental company wants you to buy their coverage because it protects them from loss. It is profitable for them and optional for you. Understanding what you own versus what you need to buy is the difference between paying nothing extra and paying $15 to $30 per day for protection you do not need.
Key Takeaways
- Your personal auto insurance often covers rental cars at no extra cost, but you need to verify this before you rent because coverage limits vary.
- Premium credit cards frequently include rental car protection that covers collision and theft, which can eliminate the need to buy the rental company's damage waiver.
- The rental company's collision damage waiver does not cover liability (injury or property damage to others), so you need separate liability coverage regardless.
- If you have no personal auto insurance and no credit card protection, buying the rental company's coverage is cheaper than risking a large bill for damage.
- Rideshare and commercial use are typically excluded from all rental coverage, so drivers for Uber or Lyft should ask their insurance company before renting.
What your personal auto insurance covers
If you own a car and carry collision and comprehensive coverage, your policy usually extends to rental vehicles at no additional cost. This means damage from an accident, theft, or weather is covered under the same deductible you pay at home. However, the word "usually" matters — some policies exclude rentals or limit coverage to a certain number of days.
Call your insurance company before you rent and ask three specific questions: Does my policy cover rental cars? For how many days? What is my deductible? Write down the answers and the name of the person you spoke with. If your policy does cover rentals, you can decline the rental company's damage waiver and save money.
One caveat: your personal insurance covers only damage to the rental car itself. It does not cover liability — injury or property damage you cause to someone else. The rental company's liability coverage is mandatory in most states, and you will pay for it whether you buy their full package or not. The question is whether you buy it separately or let your own liability coverage handle it.
Credit card rental car protection
Many premium credit cards include rental car coverage that pays for collision and theft damage to the rental vehicle. This is called a rental car reimbursement benefit or rental car damage waiver. If your card has it, you can use it instead of buying the rental company's coverage, and you pay nothing extra.
Check your credit card's benefits guide or call the card issuer and ask whether they cover rental cars. If they do, ask what is excluded — some cards do not cover luxury vehicles, trucks, or one-way rentals. Also ask whether you must decline the rental company's coverage to activate the card's protection, because some cards require you to refuse the rental company's offer in writing.
Credit card coverage typically has a higher deductible than your personal auto insurance (often $500 or $1,000 instead of $250 or $500), so it works best as a backup. If you have personal auto insurance with a low deductible, use that first. If you do not have personal auto insurance, a credit card benefit can be your primary protection.
When you should buy the rental company's coverage
Buy the rental company's collision damage waiver if you have no personal auto insurance and no credit card protection. The daily cost ($15 to $30) is less than the risk of paying thousands of dollars out of pocket for damage you cause. A single accident can result in a bill for repairs, diminished value, and loss of use — costs that add up quickly.
You should also buy coverage if you are renting a vehicle type your personal insurance or credit card excludes. Some policies do not cover trucks, vans, or luxury cars. If you are renting a vehicle outside your coverage, the rental company's waiver protects you.
Rideshare and commercial drivers should buy the rental company's coverage and also contact their insurance company before renting. Most personal auto policies exclude commercial use, including driving for Uber or Lyft. The rental company's coverage may also exclude commercial use, so you need to know what you are actually protected by before you drive.
Liability coverage is not optional
Liability coverage pays for injury or property damage you cause to someone else — a person in another car, a pedestrian, or someone's property. This is different from collision coverage, which pays for damage to the rental car itself. You need liability coverage no matter what, and you will pay for it.
If you have personal auto insurance, your liability coverage extends to the rental car. If you do not have personal auto insurance, you must buy the rental company's liability coverage. There is no way around this — you cannot legally drive without it in most states, and you cannot decline it at the rental counter.
The rental company's liability limits are often lower than what you would carry on your own car. If you have a high net worth or own property, ask whether your homeowners insurance provides an umbrella policy that covers rental vehicles. An umbrella policy can provide additional liability protection beyond what the rental company offers.
What to do at the rental counter
When you arrive to pick up the rental car, tell the agent that you have your own insurance or credit card coverage. Show them your insurance card or credit card if they ask. Do not sign anything that says you are waiving coverage you do not actually have — only waive coverage you have verified in writing before you rented.
If you are unsure whether you are covered, buy the rental company's package for that rental. It is better to pay $20 for a day you do not need coverage than to decline coverage and discover you are uninsured after an accident. You can always ask for a refund if you change your mind before you drive off the lot.
Take photos of the rental car before you leave the parking lot — the front, back, sides, and interior. This creates a record of its condition and protects you if the rental company tries to charge you for damage that existed before you rented it. Many rental companies now do this automatically with their own photos, but your own documentation is additional protection.
Frequently Asked Questions
Does my auto insurance cover rental cars in other countries?
Most personal auto insurance policies do not cover rentals outside the United States. If you are renting internationally, contact your insurance company before you travel. You may need to buy the rental company's coverage or purchase a separate international rental policy.
What if I get in an accident and I declined the rental company's coverage?
Contact your insurance company immediately and report the accident. Your personal auto insurance will handle the claim under your collision coverage, subject to your deductible. The rental company will bill you for any costs not covered by your insurance, so make sure your coverage limits are adequate before you decline their waiver.
Can I buy rental car insurance after I have already rented the car?
No. You must buy or decline coverage at the rental counter before you drive off the lot. Once you have the keys, the rental company will not sell you additional coverage. This is why it is important to verify your coverage before you arrive at the rental location.
Does my employer's car insurance cover me when I rent a vehicle?
Some employers provide coverage for employees who rent cars for business purposes, but this is not automatic. Ask your employer's human resources or risk management department whether you are covered and what the limits are. If you are renting for personal use, your employer's policy typically does not apply.
What is the difference between a damage waiver and insurance?
A damage waiver is a contract between you and the rental company that waives their right to charge you for damage to the car. Insurance is a policy that pays a third party (the rental company) for your liability. Waivers are simpler but often have more exclusions. Both serve the same practical purpose: they protect you from paying out of pocket.
